In VC DLL
function 前不需要加入 __declspec(dllexport)，要匯出的function名稱加入 .def 即可，避免name mangling
function 之 calling convertion 為 __stdcall
ex. int __stdcall GetCPUSpeed()
使用.def 作出的 Dll，可被 VC 及 VB 程式呼叫
VB 傳參數進 VC DLL
例一 : Call By Reference
In VB，若function宣告為
Private Declare Function GetStrFromVC1 "z:DllDebugDll2.dll" ( ByRef PA as integer, ByRef str1 as String) As String
呼叫
view plain
Visual Basic:
Dim strRet as String
Dim PA as Integer
Dim strOutStr as [...]
